GRAIN-BAG HOLDER.

Specification of Letters Patent. P te ted Apr. 13, 1920.

Application filed July 6, 1918. Serial No. 243,543.

To all whom it may concern:

Be it known that 1, WILLIAM JAHNS, a citizen of the United States,residing at Marathon, in the county of Marathon and State oflVisconsimhave invented new and useful Improvements in Grain-BagHolders, of which the following is a specification.

This invention relates to improvements in grain bag holders.

In carrying out my invention it is my purpose to produce a grain bagholder which will firmly grip the bag and which is adjustable bothvertically and laterally to engage with various sizes of bags.

It is also my purpose to produce a grain bag holder of a comparativelysimple construction wherein the bags may be easily attached thereto andfirmly supported thereby and also wherein a shaking movement may beimparted to the bag to settle the grain delivered therein.

Other objects and advantages of the improvement will appear in thefollowing specification and will be pointed out wlth particularity inthe appended claims.

In the drawings, accompanying this speci fication there has beenillustrated a simple and satisfactory exemplification of theimprovement, in which,

Figure 1 is a perspective view showing a grain sack secured upon aholder construct ed in accordance with my invention.

Fig. 2 is a top plan view, the sack being removed.

Fig. 3 is a front elevation of the same.

Fig. 41 is a sectional view approximately on the line 4-4: of Fig. 1.

Fig. 8 is a sectional view approximately on the line 88 of Fig. 2.

Fig. 9 is a detail sectional view approximately on the line 99;of Fig.3.

Fig. 10 is a perspective view of the clamp.

Fig. 11 is a perspective view of one of the jaws of the clamp.

The improvement contemplates the employment of a base formed of twospaced elongated pieces or beams 10 each having an oppositely disposedupstanding standard. The standards 11, while disposed near the center ofthe beams or foot pieces 10 are 7 supported by angle braces 14.

The inner faces of the wall of the standards 11 are provided withalining vertically disposed elongated slots 15 receiving therein theends of a beam or plate 16 that is secured to the lower 'ends of sidemembers 17 arranged in the slots 15, but extend above the standards. Themembers 17 provide the sides of what I will term the lower frame of thedevice, the plate 16 provides the lower member of the frame and theupper connecting member for the sides is indicated by the numeral 18.

The sides 17, at the portions thereof received in the slots 15 of thestandards are provided with vertically disposed elongated openings 19,and journaled in suitable bearings provided by transverse openings inthe upper ends of the standards 11, and passing through the saidopenings 19 is a shaft 20. This shaft is held against longitudinalmovement by suitable collars 21 secured thereon and contacting with theouter faces of the standards 11. One end of the shaft is offsetproviding the same with a crank 22, and secured to this crank is a link.23 that has its lower end loosely connected, as at 24: to a foot pedal25, the inner end of which being pivotally secured as at 26 to one ofthe foot members 10. The shaft 20 has keyed or otherwise secured thereontoothed segments 27 one of which being disposed adjacent to the innerface of each of the standards 11, while secured to the plate 16 are rackbars 28 which are engaged by the toothed segments. These rack bars areguided through suitable socket members 29 secured to the connecting member 13 for the standards 11. By this arrangement it will be seen that apressure upon the pedal 25, in a downward direction will cause the frameto be moved upwardly of the base of the device and a release of suchpressure will permit the frame, by the weight thereof resuming itsinitial position by dropping or gravitating downwardly in the slots 15of the standards. The pedal, it will be thus seen serves as a means foragitating the frame, and for the i an .the upper frame m suchadjustment.

sake of convenience the frame willhereinafter be referred to as thelower frame section.

The upper frame section is broadly indi- 'cated by the numeral andincludes flat side members 31 ofa size corresponding to that of the sidemembers ofthe lower frame The inner faces of the sides of the upperframe contact with the outer faces of the sides of the lower frame,yokes 32 being secured on the sides 31 and surrounding the sides 17 ofthe lower frame. If desired the yokes maybe centrally provided withantifrictional rollers 33 received in-and contacting with the side wallsof elongated slots 3 f on the side members 17 of the lower frame.

The sides 31 of the upper frainecare pro-i vided withelongated slots oropenings arranged in parallelism and extending longitudinally of thesaid sides. One of the side "walls provided by each of the openings 35is formed with. or has secured thereon a toothed rack 36. Journaled insuitable bearings 37 on the top member 18 of the lower frameis ashaft38. On this shaft is keyed orotherwise securedpinions 39' thatengage with the teeth of-the racks 36. The shaft projects through theopenings in the sides of the upper frame. and in the preferredconstruction of the invention, as illustrated by the drawings thetoothed racks are arranged nearer the outer face than the inner face ofthe side members, and sleeves 40 are formed on the inner faces'of thepinions 39, the sain sleeves contacting with the opposite walls providedby the openings 35 and as a consequence the said sleeves provide abearing support for the upper frame so that the slots in the lower frameand the antifrictional rollers on the yokes are not absolutelyessential.

On one end of the shaft '38 is, secured a ratchet wheel ll. The teeth ofthis wheel are engaged bya dog 42. The dog is formed angularlyon one endof a rod 3. The rod is j ournaled'in bezwings tfl on'the inner edge ofthe upper connecting member for the lower frame, and the inner end ofthe rod is arranged at an angle to provide a handle as. A spring issecured to the upper connecting member of the lower frame and:tothe-handlel-5 to retain the handle in one position and the dog inengagement with the ratchet wheel. The outer or serond end of the shaft38 is provided with a crank handle {137. By this arrangement it will beseen that ay be adjusted vertically with respectto =thelower frame andheld iii The release of the dog from the ratchet wheel will permit ofthe upper frame gravitating downwardly over the lower :frame, so thatproper adjustments betweenthe frames may be readily obtained.

'llheside members 31 of the upper frame,

at the upper edges thereof, and upon what I will'term the outer face ofthe device, are connectedby a flat vertically disposed plate 4L8 Thisplateyupon its outer face'may' be formed with a longitudinal groove, andthe opposite walls provided by the groove may be slotted longitudinally,or, if desired, and

' as illustrated by the drawings, lipped plates :9 may be secured to theouter face of the plate 48. The lips of these plates are formed upon theconfronting edges thereof 7 and provide ways for the rectangular bodyportions of the bag holdingclamps. The body of each of the clamps'isformedwith or has secured upon its outer face :a right angu- "larbracket 51, and the lower edge of each being longer than the outer stud,and between the studs the jaw is provided with springs 55. The centerand longer stud 54 hasits end up set as at 56. This up set end is preferably threaded. V

The outer jaw of each of the clampscomprises a flat plate 517 havingopenings 58 therein through which the studs project. The outer jaw ishooked by the springs so that the same is normally'held away fromtheinner jaw. Theouter jaw, adjacent'the lower edge thereof is depressedlongitudinally from its opposite sides forming the same with an inturnedU-shaped projection 59 and a U- shaped depression 60. These corrugatedportions of the upper jaw are designed to co-engage with corrugatedportions '52 and 53 of the inner jaw when the outer jaw is broughtagainst the inner jaw. 'On the up set 56 of the central stud is journaled a cam ()1 having a handle 62. Preferably this cam is formed ofstrap iron bent or coiled upon itself to provide the cam surface and thehandle. It will be apparent'that by operating the handle the cam 61 willbe brought to contact with the outer face of the outer jaw moving thesame against the pressure of the springs into contact with the innerjaw. It will be further noted, by reference to the drawings that thecorrugated surface of the inner jaw is disposed a considerable distancebelow the bracket on which the said corrugated surface is formed so thatample roomisprovided for the edge of the sack 63 when the same isclampedbetweenthe jaws. On the plate or connecting member for the sidesof theupper frame, above the upper edge of 'the said plate is arranged aa longitudinally disposed guide rod 65 the offset ends of which. beingconnected to the said plate -in any desired or preferred manner. On theguide rod is arranged for slidable movement apron plates 66 and 67respectively. Each of the plates, upon its upper edge is roundedinwardly upon itself to provide the same with a barrel 68 which isreceived on the guide rod 65. It is to be noted that each of the barrels68 is extended from the outer end of the respective apron plates lessthan one-half the length of the aid plate and that the plate 66 has itsupper edge lapping the plate 67. The outer edges of the plates are bentupon themselves providing the plates 66 with a cross sec tional U-shapedgroove 69 and the outer edge of the plate 67 with a rib 70 which isreceived in the groove 69. By this arrangement a tight joint is retainedbetween the plates, but the said plates may be folded one over theother, when the clamps are ad justed longitudinal of the upper frame, ina manner which will presently be described. The body plate of each of heclamps, or if desired the bracket on each of the body plates hasarranged thereon a hook 71, and each of the apron plates, adjacent theouter edge thereof is provided with a slot 72 receiidng the respectivehooks. By this arrangement the apron plates are not only detachablyconnected with the clamps but are retained at a desired inclination withrespect to the clamps and with respect to the frame. The plate 66 hasits inner edge notched as at 73, the notch being arranged in a line withthe hook 71 which engages the apron plate 67., so that the plate 66 canslide to fully cover the plate 67, when the clamps are adjusted for avery small sized sack.

Secured to the connecting plate for the sides of the upper frame is arack 7st. The rack is extended over the end of the device on the sidethereof provided with the foot pedal and. with the crank end of theshaft 38. Preferably the rack is in the nature of a flat slotted plateand one of the edges provided by the said slot is formed with the rackteeth. In the slot of the rack plate is arranged a lever 75, the samehaving transverse lug 7 6 which contacts with the upper face of the rackplate to hold the lever thereon. The lever has one of its edges providedwith an elongated inturned. portion forming a tooth 7 7 that is designedto co -engage with the rack teeth. The lower end of the lever is roundedinwardly and is provided with spaced openings. The upper openingreceives the offset end of a short link 78 which loosely connected tothe clamp nearest the lever, while the lower opening receives the offsetend of link 79 that is loosely connected to the second clamp. The slotin the rack plate, through which the lever passes permits of a lateralmovement of the lever to bring the tooth thereof into or out ofengagement with any of the teeth of the rack, and by proper ad justmentof the lev r with respect to the rack the tooth of the lever engagingwith a certain tooth of the rack permits of a quick and accurateadjustment of the clamps with respect to each other, and by properlyfulcruming the lever on the tooth rack one of the clamps may be movedtoward or away from the other without influencing the last referred toclamp.

The apron properly directs the grain to the sack preventing the samefilling the ways in which the clamps slide. By operating the foot pedalor lever the grain in the sack will be agitated to cause the same toproperly gravitate to the bottom of the sack and so level the grain inthe sack. The device can be operated by a single hand, and is portable.It .is thought, from the fore going, when taken in connection with thedrawings that the construction and operation of the device will be fullyunderstood, and a more detailed description thereof will not benecessitated.

Having thus described the invention, what I claim is:

1. In a grain sack holder, a base, a sectional frame thereon, adjustingmeans between the sections of the frame, agitating means between thebase and frame, longitudinally adjustable clamps carried by said frame,a hinged collapsible apron on the frame between the clamps, andconnecting means between the sections of said apron and the respectiveclamps.

2. In a grain sack holder, a base, a sectional frame supported by saidbase, means for reciprocating the frame, one section of the frame havingits sides lapping the sections of the other section, yokes secured tothe upper section and surrounding the sides of the lower section, meanscarried by the lower section and co-engaging with the up per section forvertically moving the latter, stop means for said adjusting means,spaced slidable clamps on the upper section, and a collapsible apron onthe frame between the clamps.

3. In a grain sack holder, a base, a sectional frame supported on saidbase, means between said frame and base for imparting a reciprocatorymovement to the frame, means for adjusting the sections of the framewith respect to each other, means for retaining said sections inalinement, clamps on the upper section and a collapsible apron betweenthe clamps.

in testimony whereof I affix my signature.
